The SETUP.COM Program
The SETUP.COM utility can be used from the command line to access the same SETUP functions
as the hot key code, CTRL-ALT-ESC. SETUP.COM also adds additional functionality, such as the
ability to load and store configuration set ting s to a d is k file. Thi s sa me featu re is u sed to sto re
OEM information in the configuration memory EEPROM. SETUP.COM is on the Ampro Co mmon
Utilities diskette, included with the Lit tle Board /48 6e Development Kit. See the Ampro Common
Utilities manual for more information regarding SETU P.COM u sage.

Creating Configuration Files with SETUP.COM

The Ampro SETUP utility, SETUP.COM, offers the following options for command line entry:
SETUP [-switches] [ @file.ext | Wfile.ext ]
The supported switches and their meaning are sh own in T able 2–59.

@file.ext Writes the specified file to the board’s CMOS RAM and c onf igur atio n
EEPROM. Drive and path are optional in the fil e nam e.
Wfile.ext Write CMOS RAM and EEPROM contents to the f ile sp ecif ied. T he

You can save a copy of the current contents of the board’s configuration memory to a disk file by
using the W switch. The data saved includes the entire contents of the nonvolatile configuration
EEPROM. The first 512 bits are the SETUP inf orm ation (ex cluding time and d ate), the next 512
bits are available for OEM storage. See Ampro App licat ion N ote A AN-88 05 for a de script ion o f ho w
to use the OEM storage portion of the EEPROM.
The file you create with this menu option can be used as a source for programming the
configuration memory of a Little Board/486e CPU at a later time.
As an example, the following command initializes the E EPRO M valu es w ith a p revio usly save d
configuration:
C>SETUP @SYSTEM.A
Assuming you created the file SYSTEM.A with SET UP’ s wr ite opt ion, S ETU P w ill ini tialize the
EEPROM configuration memory using the contents of SYSTEM.A.
Using SETUP with the write and read parameter s can be use ful wh en many board s mu st be
initialized automatically, or when you want to change between several predefined system
configurations.
